The Schedule xeferred to :ln these yLettere Patent and making part ofthe same.

To all whom it may concern; y

Be it known that we, CHARLES A. FITCH, of San Francisco, county ot' SanFrancisco, and WILLIAM 0. Sr, JOHN, of Oakland, county of' Alameda andState of California, have invented an Improved Ledger-Jndex; and we dohereby declare the following description and accompanying drawings aresuiicient to enable any person skilled in the' art; or science to whichit most nearly appertains to make and luse 'our said invention orimprovements without further invention or experiment.

The object of our invention is -t`ov provide a ready and convenientindex-book, which is arranged with ruled pages, each sheet beingsuiiciently stiff to support itself, so that when it is raised itwillstand vertically in front of' the .book-keeper or accountant in acom'enientposition to display the names written upon it' is had to theaccompanying vdrawings forming a part of this specification, in whichf lA represents our index-book. This book consists of a number ot' sheets,B, made of 'card-bard or other In order to better illustrate ourinvention, reference suitable paper, munberiug'at least as many as thereare letters in the alphabet. Between each of these sheets may be placedan intermediate sheet or pasteboard, a. l

The intermediate sheets a are. somewhat longer 7than the sheets B, andare placed in the book in such a position `that the extra length of eachwill project4 altogether at one end, while the other end is flush withthe ruled sheets.

The whole is then bound with asuitable cover, which protects the twosides, the back, and one endot the book, the extra length ofthelintermediate sheets be-A ingbound together at the`end C. A

A bolt, or rivet, b, passes through the lower corner of thc unbound endofthe book, passing also through the corner of each of the leaves orsheets B, thus leaving them simply held by the bolt.

Secured at some convenient point, and in the most convenient order alongthe upper edge of the sheets A, are small metallic or other suitabletags, marked as in the drawings, with the letters 0i the alphabet from Ato Z. By grasping either of these tags and drawing upward upon it thesheet to which it is at-v tached is li'tedand turned unt-il it standsupon the pivoted end, bringing itsentire length directly' before theaccountant. a

The naines ofthe persons havin gledger a( counts and the number of thepages uponwhich they occur-'are written upon the sheets B, beingalrangedupon the pages by letters according to the usual way of forminga ledgerindex, Which-can be done by taking out the bolt b and removingthe sheets, and afterward re'- turning them to their proper places.

The sheets B may be ruled or not, as most convenient. n

By constructing an index-book in the above-described manner agreatsavingof time is obtained, while all danger of soiling the ledgeritself by turning so frequently to the index, as is usual when the index.is made a part of the ledger, is obviated.

The book' presents a 'neat form, and can be readily opened and closed toany letter of the alphabet.

What we desire to secure by Letters Patent isl. An index-book having thesheets B pivoted as shown, and provided lwith the alphabetical tags,substantially as described. .4

2. The arrangement of the pivot b at the lower corner of the book,whereby the sheet raised stands upon and is kept iu position by thesurface of the desk or table, and the whole length of the sheetpresented to view, substantially as described.

. In witness whereof we have hereunto set our hands and seals.
